PHP, or Hypertext Preprocessor (originally Personal Home Page), is an open-source server-side scripting language used for developing dynamic websites and web applications. It’s extremely popular, too — more than 75% of all websites were still using PHP as of October 2022, with no signs of slowing down any time soon. It’s free to download and use and powerful enough to run some of the biggest websites on the internet (WordPress, Facebook, and Wikipedia, just to name a few).

Certificates have a limited validity time and need to be renewed once in a while. Expired certificates may impact the availability of services. MetrixInsight for NetScaler monitors the expiration state of NetScaler certificates and alarms you when they are going to expire and have been expired.

Are you aware when an administrator has forgotten to save configuration on a Citrix NetScaler device? If configuration is not saved after a configuration change it will get lost when the NetScaler appliance restarts. This can obviously have severe consequences. MetrixInsight for NetScaler will alarm you whenever unsaved configuration is detected.

When your NetScaler appliances are running in a High Availability (HA) pair you should be aware when failovers occur, as this indicates an issue on one or both of the appliances, which you need to solve before both the appliances have the same issue. In the case the latter happens, or is already the case, the appliances will fail over continuously, which is known as HA failover ‘flip-flopping’.

Many of the benefits of running Kubernetes come from the efficiencies that you get when you share the cluster – and thus the underlying compute and network resources it manages – between multiple services and teams within your organization. Each of these major services or teams that share the cluster are tenants of the cluster – and thus this approach is referred to as multi-tenancy.

Use Netdata to effectively monitor and troubleshoot the performance of NVMe (Non-Volatile Memory express) disks in your infrastructure. Preempt disk failures and take action to ensure your systems run without a glitch.

The abrupt transition to remote work that has occurred over the past few years has caused Microsoft Teams to become an indispensable application for many companies. As such, it is absolutely imperative to make sure that Teams users have a good experience, particularly with regard to call quality. Herein lies the problem. Although Microsoft has provided some rudimentary tools that can be used for user experience monitoring, those integrated tools are inadequate for enterprise use.
